To all 'w from it may camera:

Be it known. that l, Fnrnn lineman, a citizen oil the United States, residing at. Connellsville, in the county of Fayette, State oi Pennsylvania, have invented certain new and useful Improvements in lllatrix Devices tor lllolds, 0t which the following is a specification.

"lhisinvention relates broadly to molding and more particularly to molding by pressing plastic material such as glass or the like.

The principal object of the present invention is to provide a block mold with the provision of mechanism which permits figures either cameo or intagrlio to be formed upon the article being shaped. in the mold.

Another object of the present invention is a. molding device of the character specified comprising a block mold and means movable relatively to portions on the side wall of the block mold in such manner that lateral projections/or indentations may be formed on the side wall of the device being molded in the block mold.

it still further object of the present invention is a provision in pressing; molds of movable portionswhereby parts of the side wall of the mold may be I'GIIlUVQfl to permit ware having indentations or projections, as the case may be, to be molded in block molds and to be removed. there-from when the moulding operation is complete.

More specifically the present invention comprises a hlock mold for plastic material and wherein movable matrices are provide: in one of the pressing! members so that either projections or recesses may be molded in the side wall of the article being made and the article may then be removed from the block mold without injury to the article.

Another object oi? the present invention is the mold ot the character specified and wherein the movable parts are automatically operated during the movement of the parts or the molding; operation.

@ther and further objects of the present invention will in part be obvious and will. in part be pointed out hereinafter in the specification wherein like parts are indicated by like characters throughout the several figarcs of the drawings.

Realizing); that the present invention may be embodied in constructions other than those herein specifically shown and det'erial 1W0. 383,3 ll.

scribed, it is to be understood that the present disclosure is intended to be illustrative and not to be considered in the limiting sense.

Figure 1 is a view showing a mold embodying the present invention and illustratingr the pressing operation.

Figure is a view similar to Figure 1 showing the pressing operation finished.

Figure 3 is a detail view of a portion of j the mold illustrating a construction in accordance with the present inventlon wlth the figure impressingdevice operative against a portion of a tumbler or packing jar and showing the parts during the pressing operation.

Figure t is a view similar to Figure 1 showing the impression device removed, with the p lassarticle ready to be removed from the mold.

Figure 5 is a detail plan view of the impression device illustrating portions in sections.

llel'etofore in the molding or pressing as applied to glass wherein articles have been manufactured in block molds, it has been the custom to term projections or depressions by means of vertical removab e portions of the mold, usually parts known as ringr molds, so that when the ring; mold was lifted from the block mold the article shaped in the block mold would be free for removal :trom the block mold. ltn this type of construction projections or depressions could only be made on the upper part of: the article and could not be made in the body portion below the zone in which any projection or depression covered by the ring mold constructions was made. Where embossed or depressed designs were formed on the side wall on the containers below the top finish such. configurations have usually been in split molds or blow molds so that when the article was formed the entire mold might be removed from the finished article by lateral movements of the mold body. The split mold usually leaves marks on the finished ware and such molds are more e1:- pensive to manufacture and operate. Furthermore, as a rule the split molds do not operate at the same speed as the block molds.

The present invention overcomes the difiiculties oi the known prior art by providing a. block mold with a movable portion carrying the design or configuration which it is do lltl and is adapted to sired to impress upon the side wall of the article being formed. This movable portion may be arranged in such manner as to be impressed on the interior or exterior of the side wall and preferably is so arranged as to be automatically withdrawn by the ordinary operations of the machines carrying the mold. This construction permits this type of mold to be utilized on the ordinary machines without change of machine the only change being in the mold structure itself. One specific embodiment of the present invention comprises a block mold for tumblers packers ware, or the like, adapted to be carried by the ordinary glass press and whercin slidable matrix members are provided in the side wall of the mold in such manner that'the movement of the parts during the pressing operations causes actuating means fort-he slides to become eifective to withdraw the matrix from the side of the finished article when the pressing operation is completed.

Referring to the drawings, which disclose one embodiment of the invention, a detail of a portion of a glass press is illustrated and comprises a pedestal l on which is mounted a yoke 2 that is supported by frame rods 4. The yoke carries a staff 5 on which is mounted a. pressing plunger 6. A ring mold is mounted adjacent the pressin plunger and is adapted to be op erated by an air cylinder 8 and connected parts to cooperate with a block mold 9 that is mounted on the mold table 10. There are a plurality of these block molds all mounted on the mold table, as is known in the art. The block mold is adapted to be moved into operative relation to the plunger 6 and this may be accomplished as is known in the art, by means of an air pressing ram which may comprise a plunger head 11 which is operated by a suitable air cylinder 12, and is controlled by timing mechanism, not shown, which also controls the rotation of the mold table.

Referring especially to Figures 3, 4 and 5 the block mold 10 in Figure 3 is shown as being provided with an. opening which extends parallel to the movement of the mold, This opening provides a guideway for the cam slide l l. The mold is also provided with a. lateral opening that extends through the side wall of the mold and a figureblock 15 is mounted in this slideway( This figure block is provided with an opening 16, through which the cam slide extends andv one side of this opening may be inclined as at 1,7 to cooperate with the incl ned cam 18 On the figure block 15 a stubscrew 19 extends into the opening 16 rest againstthe cam tace 20. This stub screw may be held in position by a lock nut 21. From the foregolng description it will be evident that the vertical movement of the cam slide relatively to the side wall oil the block mold 9 will cause alateral movement of the ligure block 15. This figure block 15 is provided on its inner face with an ornamenta tion or the mniiguration which is illustrated as a recess When the block mold is raised into pressing position as is shown in li igures l and 8 the inner face of the figure block forms a part oi the side wall or? the mold and the upper end 13 ol the cam slide 1-.-i-

beneath a part or" the ring: mold 7 so that during the pres ing op erations the glass 211 or other plastic material. may be subjected to pressure without danger to the figure block yielding in view of the fact that the cam slide cannot rise. The recess or other couiiguiwdion. impresses its imprint on the side oi the article being made and when the, molding operation is finished and the mold returns to position on the mold table the lower end of the cam slide 14 contacts with the mold table 10 thereby lifting the cam slide and consequently causing the figure block 15 to be withdrawn from the side or" the glass or other article 27 The prcssed an ticle may now be removed lrom the mold block by means of a ware li'lt plunger 2:? in the manner that is now known to the art.

From the illustrated cmbmlinuut of the invention herewith disclosed it will be obvious to all those familiar with the art that various shapes and sizes of figure blocks may be provided in such number as ma be required around the wall of the article being made and it will also be clear that these slide blocks may also he provided on either the interior or exterior mold members as may be desired.
